Genes affected

ZBED4 (HGNC:20721): (zinc finger BED-type containing 4) Enables identical protein binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Located in cytoplasm and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ZBED4 links:

ALG12 (HGNC:19358): (ALG12 alpha-1,6-mannosyltransferase) This gene encodes a member of the glycosyltransferase 22 family. The encoded protein catalyzes the addition of the eighth mannose residue in an alpha-1,6 linkage onto the dolichol-PP-oligosaccharide precursor (dolichol-PP-Man(7)GlcNAc(2)) required for protein glycosylation. Mutations in this gene have been associated with congenital disorder of glycosylation type Ig (CDG-Ig)characterized by abnormal N-glycosylation. [provided by RefSeq, Jul 2008]

The c.542C>T (p.S181L) alteration is located in exon 2 (coding exon 1) of the ZBED4 gene. This alteration results from a C to T substitution at nucleotide position 542, causing the serine (S) at amino acid position 181 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
